Pure water through the pipeline and through separate nozzles enters the water heater (boiler) 21, located in the upper part of the internal volume of the boiler, is heated from a water jacket 7, heated to a temperature of less than 93 degrees C and supplied to household needs. When the preset boiler water temperature is reached, the automatics shuts off the gas supply to the gas burner device (GGU) and turns it on again when the temperature drops to a value determined by taking into account the automated hysteresis zone, which should not exceed 10 degrees C. Gas supply to the main burners 12 to the gas burner the device of the GGU boiler in the process of its operation automatically stops in the following cases:
